MACHINE. non sTIcKING PINS.

Specification of Letters Patent No. 16,199, dated December 9, 1856.

To all whom it may concern:

Be it known that I, CHARLES ATwooD, of the city, county, and State of New York, have invented a Machine for Manufacturing Diamond or Lilliputan Pincushions, of which the following description, illustrated by the accompanying drawings and references, is suliiciently clear and comprehensive to enable persons of competent skill to make and use my invention.

Figure l, is a side elevation a portion being sectional, Fig. 2, is a front sectional elevation, Fig. 3, is a top view, certa-in portions -being removed, Fig. t, is a sectional elevation of the chuck for holding the paper `for the pins, Fig'. 5, is an end view of the com pound cam wheel upon the top of the machine, and Fig. 6, is a cross section of the conducting channel.

The nat-ure of my invention consists in turning the pins from a perpendicular to a horizontal position by a twisted conducting channel and delivering them in a horizontal posit-ion upon a valve-way, and then measuring olf a sutlicient quantity for a row of pins in mass by a dividing or separating instrument having a double inclined plane-or a bevel and incline something after the form of an extension corner chisel, the end or corner of which enters between the pins near the head ends in the free space and, next, in separating the pins one by one in detail and rolling them along upon the rail-way for the purpose of still further separating and spacing the pins (preparatory to lowering and sinking them into a groove or platform of grooves s by the dropping of the rail-way parallel with the bottom of the guiding channels; frpm which channels or guiding grooves they are driven or inserted into the paper, bent in a U or staple shape (thus Vl) and which is moved upward, to produce parallel rows-and presents first one side of the U or plane and then the other by revolving it upon its vertical axis) to the ends of the guiding grooves in the bed; and also moving laterally at every half revolution of paper to allow the pins to be driven into it in such a manner that every alternate row upon each plane of the paper will be parallel to each other.

A is the frame work of the machine upon the bed piece B.

C, C, are the guide plates or conducting channels for transferring the pins to the falling railway-preparatory to sticking them. These conducting channels are planoconcave, as seen in the cross-section at Fig. 6, and 4at their most distant or receiving end, are set vertically, and the pins received perpendicularly, but as they approach the railway they wind aroundabout ninety degrees. The falling railway G, Gr, has a vertical motion given to it, (being hung in a fulcrum at A) by the incline of the slotted slide plate D operated by the lever E, upon the bar-or driver F. A small rectangular wire retarding spring e prevents the pins from rolling too rapidly over the support or rail-way G. The separating bars or dividing instruments H are retained in Vtheir places by the horizontal springs M, upon the bracket N, one of which is attached to each dividing instrument. These instruments are operated successively from the rear to the front, by the succession of cams I, as represented upon the wheel J moved by the rack and pinion K, L. The end of the driver F is supplied with teeth S which t within the guiding grooves. The revolving paper chuck I hung within the circular cylindrical bracket R, has also guiding channels upon its disk or upper surface which at each semi revolution of the chuck correspond to the channels bene-ath the railway. This chuck for holding and governing the paper has two deep cuts, within which the strip of paper bent or kinked to a rectangular form as represented at y Fig. 2 is inserted the paper passes over the plate Q, which has the vertical rack X upon its side keeping it in a horizontal position. Upon each se1ni-revo lution this rack is raised one tooth at a time by means of the inclined planes z', fr, which slide between the teeth of the rack. The chuck I', also receives a vibrating motion within the bracket by means of the ends of the screws N N which act as cams upon a knob upon the chuck the object of which is to so change the position of the paper that each successive row may be set at an angle to each other corresponding to the shape of tains them.

a diamond, which gives it the name of the diamond pin cushion.

The rack T upon the pinion U gives to the chuck I a semi-alternate rotary motion. This rack is thrown in and out of gear by the slide V, which takes opposite sides of the pin V in passing to and from the pinion in consequence of a spring guide which reverses by means of the pin V', or the same effect may be produced by revolving the pinion upon its shaft and operating the shaft by means Vof a dog and catch (or ratchet wheel with two teeth upon it.)

The operation of the machine is as follows: The pins are first received within the upper part of the twisted conducting channel from the shoe and hopper which con- This conducting channel arranges them in a perpendicular position in the ordinary manner, as represented, but as they slide or are driven downward toward .the guiding channels, they are changed from `changing or turning the pins preparatoryto delivering them upon a railway and still preserves the order of their arrangement. The pins are rolled upon the railway G in sufficient number to form a line or row across the paper. If too great a number should at any time be received the'surplus will be thrown off in front of the machine. This requisite number is designated by a kink in the retarding spring e which checks the flow of pins upon the railway until the first of the series of dividing instruments which is pressed down by the cam roller separates the requisite number in mass for rthe rowthe next dividing instrument measures off all but one of the former number, the next all but two-and so on-until each pin in the row is separated from its neighbor by one of the series of dividing instruments. The form of the dividers will be understood by reference to the drawings, Figs. 1 and 2 the base being cut so as to form a bevel and an acute corner toward the head of the pin-the bevel side of the instrument being toward the mass of pins to be separated. The thickness of these instruments nearly corresponds to the distance from one channel or guiding groove to another. As these instruments commence to separate the pins at the free space near the head a slight bend or irregularity in the form of the pin will not prevent it from being properly arranged:

for the guiding channel by the instruments. The instruments being all pressed down by the cams upon the cam wheel and the pins all separated from each otherthe cam wheel is stopped and the lever E is operated which moves the bar F and the slotted slide plate D. The inclination of the slot allows the rail-way to fall and thus bring the row of pins, within the guiding grooves F. Being still continued the driver with its teeth within the guiding channels takes the whole row of pins at the same time to the paper. A small rectangular piece of paper y bent into a staple or U shape, forms the cushion. The two ends of this staple shape paper are pressed down into the chuck and the side of the paper 0 corresponding with and resting upon the horizontal plate Q upon the top of the chuck. This plate being attached to the rack X raises the paper the distance between rows of pins at each semi-revolution as the rack passes over either of the inclined planes upon the end of 1, r, which slide between the teeth of the rack as above stated.

It will be observed by the action of the rack and pinion T, and U, the paper is brought to the proper position to receive the pins when they are inserted by the driver through both pieces of paper. The pins will thus be set in alternate rows rst of heads and then of points in diamond form upon each side of the paper, the heads projecting beyond the points to prevent injury of the latter by Contact. The pins and paper in this form are removed from the machine and another piece of paper put in their stead. The mode of operating the cam wheel is by an ordinary rack and pinion as represented which may be moved by a handle upon the rack or by an intermediate slotted lever as represented at R, Fig. 3.

A change in form and mode of operation in this machine may be easily effected without changing its essential features or invention-by having two conducting channels two sets of dividing instruments and thin attachments-one feeding upon one side of the paper chuck and the other upon the other side thus avoiding the necessity of turning the paper chuck.

2. The falling rail-way Gr as described for the purpose set forth.

3. The separating, measuring, and spacing bolts, Vor instruments, terminating in a double incline plane in the manner subst-antially described.
